The LTC2053HMS8 is a high precision instrumentation amplifier. The CMRR is typically 116dB with a single or dual 5V supply and is independent of gain. The input offset voltage is guaranteed below 10μV with a temperature drift of less than 50nV/°C. The LTC2053HMS8 is easy to use; the gain is adjustable with two external resistors, like a traditional op amp.
The LTC2053HMS8 uses charge balanced sampled data techniques to convert a differential input voltage into a single ended signal that is in turn amplified by a zero-drift operational amplifier.
The differential inputs operate from rail-to-rail and the single-ended output swings from rail-to-rail. The LTC2053HMS8 can be used in single-supply applications, as low as 2.7V. It can also be used with dual ±5.5V supplies. The LTC2053HMS8 requires no external clock, while the LTC2053-SYNC has a CLK pin to synchronize to an external clock.
The LTC2053HMS8 is available in an MS8 surface mount package. For space limited applications, the LTC2053HMS8 is available in a 3mm × 3mm × 0.8mm dual fine pitch leadless package (DFN).
